  1. 1. NASA Engineering of Systems Excellence Initiative S J Kapurch Program Executive Officer Systems Engineering 7 Feb 2007
  2. 2. PurposeOverview– OCE Initiatives– Policy in context of other effortsMulti-Faceted Approach– Highlight key elements– Integration of Related Efforts
  3. 3. The Environment Acquisition streamlining of the 90’s – The Good, the Bad, & the Ugly Nature abhors a vacuum – ISO-15288, IEEE-1220, EAI-632=Standards quagmire Maj. Gen. Craig Cooning, the Air Forces Director of Space Acquisition at the Pentagon – "We walked away from some of the things that served us very well. When you did away with that, you did away with the common language that engineers spoke. So, what we are trying to do is to reinstate those processes that served us well--not to go overboard--but to do it selectively." (21 October 2004)Like other organizations, NASA tossed out many processes & procedures during acquisition streamlining.
  4. 4. System Engineering Issues– Failure Review Boards have consistently pointed to lack of SE CAIB – “Organizational causes of this accident … cultural traits … detrimental to safety … allowed to develop including: …reliance on past success as a substitute for sound engineering practices …” -CAIB, Executive Summary Other Recent NASA Projects – “…., the root cause was not caught by the processes implemented by the project – CDR was too high level to adequately assess design…too little time to perform an adequate assessment – ….Although training was widely available, poor requirements are still common – “… likely cause for the failure of the system was a faulty design …switches … improperly installed on a circuit board” – “ the mishap occurred mainly because of failures in SE process….and is known to be the cause of several recent failures”
  5. 5. Complexity is a Major IssueIntegration of systems create a majorproblem with complexity– As more systems are added, the interfaces grow in a non-linear fashion– Many of the existing systems were not built for these interfaces– Conflicting or missing interface standards make it hard to define interface interactionsSystems engineering must deal with thiscomplexity– End-to-end systems engineering is needed, including “reengineering” of legacy systems– Robust M&S, verification and validation testing are A must
  6. 6. Specific NeedsNeed: Consistency in basic approach to systems engineering.Need: Agency wide framework of recognized best practices that guides the engineering of program and project products and capabilities.Need: Common systems engineering terminology and definitions to enhance communication and collaboration among engineering teams across the Agency and with external partners and customers.Need: Basis for assessing and continuously improving systems engineering capabilities.
  7. 7. Response: Systems Engineering Excellence Initiative• Systems engineering working group (SEWG) - POC at centers and MD’s for SE efforts - Plan, develop and execute the Initiative. - Coordinate project products within members’ centers• Engineering management board (EMB) - provide project oversight and approvals.• Mission directorates & centers - Provide members of the SEWG. - Provide needed support for reviews, pilots and assessments. - Verify suitability for accomplishing programs and projects.• Customers • NASA engineering community • Advanced technology teams • Payload developers • OCE • MD and Center management • Program and project managers • External partners
  8. 8. Response: The License. . . TERMS ofSEWG CHARTER REFERENCE The SEWG: “… This Is chartered by EMB, Framework will in support of Strategic describe the Plan to develop and requirements for SE implement a common processes required framework for systems engineering to engineer products in NASA and capabilities …”
  9. 9. GoalsStimulate and enable the development and advancement of a sound systems engineering capability necessary for success in fulfilling NASA Mission’s Ensure continuous improvement of the NASA engineering workforce through relevant education, training and work experiences. Ensure sound and effective discipline and systems engineering Agency-wide. Provide value-added cross-cutting products and services that enable the infusion of technology, knowledge, and capabilities to support innovation in engineering and push the state of the art. Increase participation, membership, and leadership in recognized national and international engineering organizations. Integration of Software.
  10. 10. Expected BenefitsEnable and foster excellence in systems engineeringcapabilities to:– Formulate feasible program and project concepts.– Deliver required products and services to NASA customers.– Make timely acquisition of enabling products and critical technologies.– Reduce risk in system development and deployment.Enable more effective communications andcollaboration within NASA and with external partnersand customers.Conduct effective assessment and improvement ofsystems engineering capabilities.Change the culture to represent the needs of one NASA,and not the unique needs of a particular Center.Develop strategic focus for advanced engineeringenvironments.
